first up, just so you know, I (and probably most other people) started grey knight because of the terminators! As such I decided to go for a terminator heavy army, not worried about how competitive it is!

Stern9 * GKT (1 with incinerator)

GKGMw/ p hood4 * GKT (1 with psycanon)

GKJ4 * PAGK

GKJ4 * PAGK

GKLR

GKLRC

army only has basic troops and wargear but 15 GKT and 2 LR's, lets see the heretics handle that!

Looks like a pseudo-Deathwing army. Should be fun to play. You might want to think of fielding 3 5-man GKT squads for more flexibility. If not, I'd run at least one six-man GKT squad so you have the option of getting the most out of the Crusader. You'll have a tough time foot-slogging or if deep-striking your Termies you'd be hooped if your rolls go bad.

haven't got the spare points for a brother captain needed for the 3rd GKT squad but that's a good point about making the GM's squad 6 man to go in the LRC, means I can keep the 'godhammer' stationary and keep up the LC barrage!

^^ Long as you got in some slaughtering with your termies! Personally, I'd opt to try and make a specialized mission where your termies can be holding out against waves of infantry or something. They will sadly get swamped in competitive play, and bad dice rolls spell their doom.

Still, I look forward to when I can try a full Terminator list as well Glad you had fun Brother!
